DNA (Deoxyribonucleic Acid) is a molecule that contains the genetic instructions necessary for the growth, development, functioning, and reproduction of all known living organisms. DNA is a long, double-stranded molecule composed of four nucleotide building blocks: adenine (A), cytosine (C), guanine (G), and thymine (T). The structure of DNA is often referred to as a double helix, where two strands of DNA are wound together in a spiral shape, with the nucleotide bases forming pairs and connecting the two strands. Adenine pairs with thymine (A-T), and cytosine pairs with guanine (C-G), held together by hydrogen bonds. This base-pairing arrangement allows DNA to carry and store genetic information in the sequence of its nucleotide bases, which form a genetic code. DNA carries the genetic information that determines an organism's inherited traits from one generation to the next through a process called DNA replication and cell division.

Official Solution:
RNA translates genetic information from DNA into proteins, while DNA stores genetic information and carries instructions for protein synthesis.
• Tab 3 states that RNA translates genetic information from DNA into proteins, and that DNA stores genetic information and carries instructions for protein synthesis. Thus, this statement is supported.
DNA is found primarily in the nucleus of cells, with a small amount in mitochondria.
• Tab 3 states that DNA is found primarily in the nucleus of cells, with a small amount in mitochondria. Thus, this statement is supported.
RNA is a nucleic acid made up of a chain of nucleotide building blocks, similar to DNA, but it has some important differences in structure and function compared to DNA.
• Tab 2 states that RNA is a nucleic acid made up of a chain of nucleotide building blocks and differs from DNA in both structure and function. Thus, this statement is supported.
RNA performs functions such as catalyzing chemical reactions or regulating gene expression.
• None of the tabs mention RNA catalyzing chemical reactions or regulating gene expression. Thus, this statement is not supported.
DNA can be found in the nucleus of cells in most living organisms.
• Tab 3 states that DNA is found in the nucleus of cells in most living organisms. Thus, this statement is supported.
Correct answer:
All of the following statements are supported by the information provided above EXCEPT. "RNA performs functions such as catalyzing chemical reactions or regulating gene expression."
